Eagle Tool USETD75054 in. Dirt Auger, 3/4 in. head with 54 in. shank included, Made in the USA

This bit bored right through our Missouri clay and actually went through some small roots and gravel in the dirt. It flexes alot in order to get it going horizontally and then it just follows it's own path. Just barely big enough to force a 1/2" plastic conduit through it (with some help from a sledge hammer and wood block). Worth the cost for the work it saved me. I used a 1/2" electric drill rather than a battery drill and it's power made a difference.

Wow, I rarely take the time to upload pictures and write bad reviews, but for this one I had to take the time to do so. This bit is garbage. I got de 50+ inch & 3/4 size. This thing can't even finish a single hole (even straight). The picture I took was almost 30 seconds of constant drilling at all speed you can imagine just to see if the teeth would grab the wood at some point.Again, do not buy, it's a waste of time and energy. If you notice, this bit doesn't have the spiraled cone at the top which make it spin on itself on the piece of wood and nothing happens.I am extremely dissapointed with this purchase and I am returning it right away.

I was very impressed with this auger and the extension I got. I ran a 9’ hole under my driveway and pounded through PVC to follow. In the photo a drilled towards to hole, not from it like the bit is laying. My biggest fear was losing the bit off the extension while digging, but the set screws held it on great and I was able to be very aggressive with drilling. Full speed while pushing and pulling with no problems. The bit and extension were packaged really well too, triangular boxes to avoid bending.I will say that you need a pretty roomy access pit behind your hole’s path to flex enough and avoid a diagonal downward hole (if you’re trying to drill horizontally). I used a laser level to line up my bit, and a board with weights to counter flex the bit and I ended up within 3/4” of where I wanted my hole. I didn’t put as much effort into my first try and my hole was probably 4 or 5 feet deep by the time I tried to run 9’ horizontally.

Just wiah it had a more agressive bite, takes everything you've got and a lot of time to get started thru an engineered joist.

Worked just as expected. Requires a powerful drill with high torque if using the entire length of the bit underground.
